Abstract

Apparatuses and methods for controlling a reader communicating with a device. A method for an Internet of Things (IoT) reader to communicate with a device includes receiving, from a base station (BS), first information related to a downlink (DL) reception or an uplink (UL) transmission between the IoT reader and the BS, receiving, from the BS, second information related to a reader-to-device (R2D) transmission or a device-to-reader (D2R) reception between the IoT reader and one or more devices, receiving, from the BS, third information related to executing a command, and transmitting a physical reader-to-device channel (PRDCH) to the device. The PRDCH indicates information related to executing the command. The PRDCH is device-specific to the device of the one or more devices, device-group-specific to the one or more devices, or common to all devices receiving the PRDCH. The method further includes transmitting, to the BS, fourth information related to execution of the command.
